Electrochemical Tuning of Electronic Structure of C60 and C70 Fullerene Peapods: In situ Visible Near-Infrared and Raman Study.
Original language description
The population of valence-band electronic states of fullerene peapods (C60@SWCNT and C70@SWCNT) was tuned electrochemically in 0.2 M LiClO4 + acetonitrile. Electrochemistry of peapods is dominated by their capacitive charging without distinct faradaic processes. In-situ Vis-NIR spectra of C60/C70 peapods are similar to those of empty nanotubes. Electrochemical charging causes reversible bleaching of the transitions between Van Hove singularities. This bleaching is mirrored by quenching of resonance Raman spectra in the regions of tube-related modes. The Raman modes of intratubular C60 exhibit considerable intensity increase upon anodic doping of peapods, but these Raman modes are not enhanced at cathodic charging. In contrast to that, C70@SWCNT does not show any enhancement of Raman intensities at both anodic and cathodic potentials. All the relevant Raman modes of intratubular C70 show symmetric charge-transfer bleaching as the tube-related modes.
